溴乙酰苯并15冠5和酮醚型双冠醚的合成

Synthetizing bromoacetylic benzo-15-crown-5 and biscrown of keto-ether type

以多聚磷酸 (PPA)为催化剂和反应溶剂 ,合成了溴代乙酰型取代苯并冠醚 ( )。以合成的( )为原料 ,邻苯二酚为桥联前体 ,合成酮醚型双冠醚 ( )。2种合成产物由 IR、MS和元素分析鉴定了结构。

Bromoacetylic substitution benzo 15 crown 5(Ⅰ) had been synthesized with polyphosphoric acid (PPA) as catalyst and solvent.Biscrown (Ⅱ) of keto ether type was prepared from (Ⅰ) and pyrocatechol in Me 2CO and in the persence of K 2CO 3.The two products were characterized by IR,MS and elements analysis.
